Performance verification procedures

NOTE.

If your instrument firmware version is v1.02, it should be updated before performing the performance verification procedures.Download the latest firmware from www.tek.com/software.

The following three conditions must be met prior to performing these procedures:

■ The instrument must have been operating continuously for twenty (20) minutes in an environment that meets the operatingrange specifications for temperature and humidity.

■ You must perform a signal path compensation (SPC) before beginning these procedures. If the operating temperaturechanges by more than 10 °C (18 °F), you must perform the signal path compensation again.

■ You must connect the instrument and the test equipment to the same AC power circuit. Connect the instrument and testinstruments into a common power strip if you are unsure of the AC power circuit distribution. Connecting the instrument andtest instruments into separate AC power circuits can result in offset voltages between the equipment, which can invalidatethe performance verification procedure.

The time required to complete the entire procedure is approximately one hour.

WARNING. Some procedures use hazardous voltages. To prevent electrical shock, always set voltage source outputs to 0 Vbefore making or changing any interconnections.

Self testThis procedure uses internal routines to verify that the instrument functions and passes its internal self tests. No test equipmentor hookups are required. Start the self test with these steps:

1. Disconnect all probes and cables from the instrument inputs.

2. Push the front-panel Default Setup button to set the instrument to the factory default settings.

3. Push the Utility menu button.

4. Push the Utility Page bezel button, the Diagnostics bezel button, the Self Test bezel button, and turn Multipurpose knob a toselect Loop Times.

5. Push the Multipurpose knob a to select Loop Times, and turn the Multipurpose knob a to select Loop 1 Times.

6. Push the Multipurpose knob a to set the Loop Times to 1.

7. Turn Multipurpose knob a to select Run Self Test, and push the Multipurpose knob a to start the self tests.

8. Wait while the self test runs. When the self test completes, a dialog box displays the results of the self test.

9. Push the Menu Off button to clear the dialog box and Self Test menu.



Signal path compensation (SPC)This process corrects for DC inaccuracies caused by temperature variations and/or long term drift.

1. Remove all input signals (probes and cables) from channel inputs. Input signals with AC components adversely affect SPC.

2. Push the front-panel Utility button, and then push the Utility Page bezel button.

3. Push the Calibration bezel button.

4. Turn the Multipurpose button a to select Signal Path, and then push Multipurpose knob a to select Calibration Signal Path.

5. Push the Compensate Signal Paths bezel button.

6. Wait while the Signal Path Compensation runs. On completion a dialog box informs you whether the Compensationcompleted successfully or not.

7. Push the Menu Off button to clear the dialog box and Self Test menu.

Check bandwidthThis test checks the bandwidth of all input channels.

1. Connect the output of the leveled sine wave generator (for example, Fluke 9500) to the channel 1 input as shown:


3. Push the front-panel Trigger Menu button.

4. Push the Coupling bezel button, and then use the Multipurpose knob to select and then set Noise Reject (DC LowSensitivity).

5. Push the front-panel Trigger Menu button.

6. Push the Source bezel button and use Multipurpose knob a to select the channel being tested as the trigger source.

7. Push the Menu Off button, so you can see the screen.

8. Push the channel button (1, 2, 3, or 4) for the channel that you want to check.

9. Push the Probe Setup bezel button, and then use the Multipurpose knob to select Set to 1 X.

10. Push the front-panel Measure button, and then push the bezel button for the channel you are testing.

11. Use Multipurpose knob a to select the Peak-to-peak measurement.

12. Turn the Vertical Scale knob to set the vertical scale to 500 mV/div.

13. Turn the Horizontal Scale knob to 400 µs/div.

14. Set the leveled sine wave generator frequency to 1 kHz.



15. Set the leveled sine wave generator output level so the peak-to-peak measurement is between 2.98 V and 3.02 V.

16. Set the leveled sine wave generator frequency to:
